Hi Guys Hope I have posted this in the correct place. First ski trip to Japan booked for Jan 2014, will be staying for 3 nights in Tokyo before heading north. Will be 2 adults ans 2 kids. Was hoping someone might have a few recommendations for accommodation areas to stay. looked on the usual sites booking, hotel tripadvisor but struggling with finding a room which can take all 4 in one room/ thanks in advance Richard
